Two more sequences from King Co were released tonight at GISAID. One, BetaCoV/USA/WA-S2/2020, was released by the Seattle Flu study, and the other, BetaCoV/USA/WA6-UW3/2020, was release by the University of Washington. 

Like the sequence released earlier, BetaCoV/USA/WA4-UW2/2020, they match the two Snohomish sequences (from 35M and 17M) via the two polymorphism that define the lineage (C8782T and T28144C) and the rare polymorphism (C18060T).   

However, all three of the sequences released today also have two unique polymorphisms (C17747T and A17858G) indicating they are all from patients linked to the long term care facility (LTCF) in Kirkland, Washington and their infections were due to a single introduction
